When you think of resins, you may think of the word "plastics" as a synonymous term for a particular group of materials with shared physical and chemical characteristics. However, just as metals — from lead and iron to silver and gold — do not all behave, conduct, or oxidize in the same way. Similarly, resins are vastly different in their diverse chemical structures and commercial applications.
From milk containers to airplane components, the varied uses of resins — along with the different fillers added to modify them — make for practically endless applications. While a majority of the industrial processes employed to produce resins are quite complex and precise, at their core, a majority of resin applications involve modification with resin additives producing an end-product with very specific desired properties.
Like metals and metal alloys, alloyed resin systems, i.e resins mixed with resin additives, are as diverse in application usage as systems based on metal alloys. While bronze may have given humanity the Bronze Age, only fairly recently have lightweight alloys given us jet engines and fuel cylinders.
When you need resin additives with unique characteristics, you can trust Brenntag North America as your distributor of high-quality solutions from a large and varied inventory.
What Are Resin Additives?
Thanks to resin additives’ unique characteristics, there are seemingly countless additves on the market today, with new ones constantly being developed for specialized purposes. Based on volume and desired physical properties, most resin additives take the form of a functional filler powder that can be added to plastic pellets sometime before, during, or shortly after their stages of processing.
Even for something as simple as epoxy resins and hardeners, the curing stage — during which two distinct oligomers react and cross-link to typically produce a hard coating or adhesive — serves to create a compound that will then fulfill a specific outcome, such as electrical or thermal insulation.
While today’s resin additives are numerous, what follows are some of their most common groups and classifications:
- Antimicrobial Additives: These additives help produce plastics that resist the growth of bacteria. Think of the plastic curtain in a shower as an example.
- Antioxidant Additives: These types help make products less susceptible to UV damage and wear from exposure to harsh elements. The result is a wide variety of automotive and marine parts and components.
- Colorant Additives: As their name implies, these additives are used to produce any number of vibrant colors.
- Flame Retardant Additives: Flame retardant additives make certain plastics more resistant to high temperatures and open flames. Think of smoke alarm components as well as breathing and firefighting apparatus.
- Foaming Additives: Have you ever wondered how polystyrene turns into Styrofoam? Simply put, a foaming additive causes the plastic to become lighter by trapping pockets of air during its processing.
In addition to these resin additives, many others help make various products that can withstand impacts, be elastic, or even prevent static shock.
